Copper drain pipe
We are re-doing our kitchen in a mid-1960s condo building. The building requires that the connection to the supply line be copper. The building did this but then I noticed that they also the old drain pipe (not sure what material it was) with a copper drain pipe. I thought I heard at some point that copper drain pipe is no good because it can corrode. Should I be asking them to do something different than the copper for drain pipe?? I don't want to have to re-do the piping in a few years if copper drain pipes will cause problems.
